Itís not very big approx. 2 inches, was hoping there was something we could do ourselves.
Anymore thoughts?

If it's truly a crack and not a scratch, filling it probably won't hold up. The floor sustains quite a bit of weight in a small area, when a body is standing right on that area. Of all the fiberglass work I'm NOT willing to do on Ten Forward, I think I'd attempt to do the shower floor. One thing if I screwed it up where it looked bad, I'd just cover it up with a rug!

We had something that look like a crack on our bathroom floor but upon further examination it was only a fine gel coat crack. Never got any worse that I could remember and because its only the gel coat and not the fibreglass it will never leak.
I kind of viewed it like the first scratch or door ding on your new truck.

Before our trailer we had a camper we bought used . The shower pan had a cracking in the pan . I repaired it with fiberglass mat cloth we had from making aquariums .Got some material from a boat supply . Redid the pan bottom . That was in use for 12 years before we sold because we bought the Escape .taped around the drain .coated the bottom which was yellow clear , could see the mat , then coated with gel gloss . I redid the whole bottom though . Really don't know how bad yours is but the video instructions would also work .it really isn't hard to do . I would want mine fixed if mine . It would bug me . Pat

If it's a real crack, I'd fix it as shown above then add one of the wooden floor mats some folks use to keep the weight off that spot. I;d worry the flexing from standing on it would just crack it again.
